maybe check to see if your iac solenoid is working,then maybe check your egr valve,disconnect hose to egr valve at idle and see if there is vacuum on hose coming off the egr solenoid,if there is then the solenoid is bad,had this problem before and disconnected this hose and it smoothed out and put a new solenoid on and was good then on...also maybe double check all your vacuum hose connections..and the two hose clamps at the blow off valve... retorque sc and intake bolts after heat cycle....hope this may help...jess
